Abstract
During the last few years more and more electrical devices are being integrated into automotive vehicles. For this reason, an assessment of the Specific Absorption Rate (SAR) for a person placed inside a vehicle is crucial to comply with human safety regulations. SAR values depend in general on the automotive environment specifically on vehicle models and device design. A method for the preliminary assessment of SAR, that could be used in the design phase of devices by resorting to the link between measurement and simulation, is presented. It allows to reduce design time and cost. The proposed technique consists of a single measurement of a prototype, then the measured device is modeled as a NF source that is imported in CEM tools for SAR calculation. In this paper the SAR assessment is demonstrated on a roof-mounted antenna system designed by Calearo and integrated in a portion of a car model.
